Wind power generation device

Abstract

A wind power generation device includes a wind blocking structure, which is in a box-shaped structure fixed on ground by a bottom plane thereof; a wind vane rotating body including a rotating shaft and vanes fixed on the rotating shaft and arranged at equal angle intervals, wherein the rotating shaft is mounted on two bearings of the wind blocking structure, and the vanes are rotatable inside the box-shaped structure; a power generator connected to the rotating shaft and fixed on the box-shaped structure by a linking plate. When wind blows to the wind blocking structure to rotate the wind vane rotating body, the power generator is driven by the rotating shaft to generate electrical power. The wind power generation device can include at least two wind vane rotating bodies, or area enlarging structures added on the vanes, to increase windward areas of the vanes.

Description

[0001]This application claims priority for Taiwan patent application no. 108128665 filed on Aug. 12, 2019, the content of which is incorporated by reference in its entirely.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a wind power generation device, and particularly to a power generating device which utilizes vanes fixed on a rotating shaft of a wind vane rotating body to withstand wind, so that the rotating shaft can be rotated to drive a power generator to generate electrical power.2. Description of the Related Art[0003]The kinetic energy of air flow is called wind energy, which is a kind of reusable energy generated by air flow. In general, wind energy is a form of energy extracted from wind, for example, wind turbines can be used to generate electrical power, windmills can be used to generate mechanical power, wind pumps can be used to pump or drain water, or sails can be used to propel ships. In the Middle Ages and Ancient times, pe...

AI Technical Summary

Benefits of technology

The present invention aims to provide a wind power generation device that can capture more wind power to generate more electrical power by controlling the rotating paddles in a horizontal paddle method to prevent from producing air resistance even in an upwind condition. The wind blocking structure includes a plurality of holes to reduce static air resistance and increase power generation efficiency. The area of the vane can be enlarged in a downwind condition and retracted in an upwind condition, and a flexible cloth can be connected between the vane and the area enlarging structures to withstand the pushing force of wind. The device can generate more electrical power using the increased pushing force to drive the power generator.

Problems solved by technology

The front plate is in a flat plate shape and serves as a windward side of the box-shaped structure, and when wind appears in front of the wind blocking structure, the vane above the rotating shaft can withstand wind, and the other vanes below the rotating shaft do not withstand wind because the front plate of the wind blocking structure blocks the wind.
